Product details
Overview
ADM6710JARJZ-REEL7 from Analog Devices is a high-accuracy quad-voltage microprocessor supervisory circuit in a 6-lead SOT-23 package, monitoring up to four supply rails with factory-set and adjustable thresholds. It features 5% threshold tolerance on IN1 (adjustable), IN2 (3.3 V), IN3 (2.5 V), and IN4 (adjustable), 200 ms typical reset timeout, open-drain active-low RESET output with 10 µA internal pull-up to IN2, and operates across −40°C to +125°C for industrial-grade system reliability.
For engineers reviewing the ADM6710JARJZ-REEL7 datasheet, ADM6710JARJZ-REEL7 pinout, ADM6710JARJZ-REEL7 application, or ADM6710JARJZ-REEL7 equivalent, this device supports precise power-rail monitoring in multi-supply embedded systems where deterministic reset assertion, glitch immunity, and extended temperature operation are critical selection criteria.
Technical Context
The ADM6710JARJZ-REEL7 uses internally trimmed comparators with 0.62 V reference to support adjustable thresholds via external resistor dividers on IN1 and IN4, while IN2 and IN3 are fixed at 3.3 V and 2.5 V respectively. Its UVLO detection includes 0.3% hysteresis and operates with input voltage validity down to 1 V on IN1 or IN2.
Reset assertion is triggered when any monitored input falls below its threshold; deassertion requires all inputs to exceed thresholds plus a 200 ms timeout. The open-drain RESET output pulls low to GND and is pulled high internally to IN2 (not VCC), enabling flexible logic-level interfacing without external pull-ups in many cases.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Monitoring | Four independent inputs: IN1 (adjustable), IN2 (3.3 V), IN3 (2.5 V), IN4 (adjustable) |
| Threshold Accuracy | ±5% tolerance on all four inputs - ensures reliable reset timing under voltage droop conditions |
| Reset Timeout | 200 ms typical - guarantees sufficient processor hold time after power stabilization |
| Operating Temp | −40°C to +125°C - validated for automotive under-hood and industrial control environments |
| Quiescent Current | 35 µA typical - enables use in always-on power domains without significant battery drain |
| RESET Output Type | Open-drain with 10 µA internal pull-up to IN2 - simplifies interface to diverse logic families |
| Input Validity Range | RESET remains valid as long as IN1 ≥ 1 V or IN2 ≥ 1 V - maintains supervision during brown-out recovery |
Pinout & Package
ADM6710JARJZ-REEL7 is housed in a RoHS-compliant 6-lead SOT-23 (RJ-6) package, measuring 2.90 mm × 1.60 mm × 1.15 mm, with gull-wing leads and JEDEC MO-178-AB compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN1) | Adjustable voltage monitor input | Accepts external resistor divider to set threshold down to 0.62 V; must be tied > threshold if unused |
| 2 (IN2) | Fixed 3.3 V monitor input & power supply | Powers the IC and monitors 3.3 V rail; internal pull-up for RESET references this node |
| 3 (IN3) | Fixed 2.5 V monitor input | Dedicated comparator for 2.5 V rail; no internal bias current path to VCC |
| 4 (IN4) | Adjustable voltage monitor input | Second adjustable input (same 0.62 V reference); requires external divider for >0.62 V monitoring |
| 5 (GND) | Analog and digital ground reference | Common return for all comparators and RESET driver; must be low-impedance |
| 6 (RESET) | Active-low open-drain reset output | Asserts low on undervoltage; remains low for 200 ms after recovery; sinks up to 2 mA |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent voltage monitoring | Simultaneously supervises 3.3 V, 2.5 V, and two user-defined rails - eliminates need for multiple discrete supervisors |
| Factory-trimmed thresholds | IN2 and IN3 thresholds laser-trimmed to ±5% - removes calibration overhead in production |
| Glitch-immune UVLO detection | Rejects transients <100 µs at 100 mV overdrive - prevents spurious resets in noisy power environments |
| Extended temperature operation | Full specification over −40°C to +125°C - qualified for under-chassis and motor-control applications |
| Low-power supervision | 35 µA ICC enables integration into battery-backed or energy-harvesting subsystems |
Applications
| Industrial PLC Controllers | Automotive ADAS ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6715AATA+T | Fixed 3.3 V/2.5 V/1.8 V/1.2 V thresholds; no adjustable inputs; 140 ms min timeout | Lacks flexibility for non-standard rail voltages; better suited for fixed-architecture designs | Select when all rails match standard values and layout space permits larger 8-pin TDFN package |
| TPS3808G33DBVR | Single 3.3 V supervisor with manual reset; no multi-rail capability; 200 ms timeout | Requires three additional devices to match ADM6710JARJZ-REEL7's quad monitoring | Choose only for cost-sensitive single-rail applications where board area is not constrained |

FAQ
What voltage rails does the ADM6710JARJZ-REEL7 monitor?
The ADM6710JARJZ-REEL7 monitors four independent voltage rails: IN1 (adjustable via external resistor divider), IN2 (factory-set to 3.3 V), IN3 (factory-set to 2.5 V), and IN4 (adjustable). All thresholds are specified with ±5% tolerance, and the device asserts RESET if any monitored rail drops below its respective threshold. This configuration is explicitly defined in the Ordering Guide for ADM6710JARJZ-REEL7.
Does the ADM6710JARJZ-REEL7 require an external pull-up resistor on the RESET pin?
No, the ADM6710JARJZ-REEL7 includes a 10 µA internal pull-up to IN2, eliminating the need for an external pull-up in most applications. The RESET pin is open-drain and remains valid as long as IN2 ≥ 1 V. An external pull-up may be added only if interfacing with a higher logic voltage (e.g., 5 V), but it will override the internal pull-up - a design choice confirmed in the RESET Output Configuration section of the datasheet.
What is the operating temperature range for the ADM6710JARJZ-REEL7?
The ADM6710JARJZ-REEL7 is fully specified and tested over −40°C to +125°C, meeting extended industrial and automotive under-hood requirements. This range is guaranteed per Absolute Maximum Ratings Table 2 and validated across all electrical parameters in the Specifications table, including threshold accuracy, reset timeout, and input current.
How does the ADM6710JARJZ-REEL7 handle power supply glitches?
The ADM6710JARJZ-REEL7 incorporates inherent glitch immunity: its comparators reject transients shorter than ~100 µs (per Figure 7), and the 0.3% threshold hysteresis prevents chatter during slow-rising/falling edges. Additionally, the datasheet recommends adding a 0.1 µF capacitor from IN2 to GND to further suppress noise - a technique validated in Typical Performance Characteristics.
Can unused inputs on the ADM6710JARJZ-REEL7 be left floating?
No - unused inputs on the ADM6710JARJZ-REEL7 must never float or be grounded. For fixed-threshold inputs (IN2, IN3), connect to a supply > their threshold (e.g., tie unused IN3 to 3.3 V). For adjustable inputs (IN1, IN4), connect via a 1 MΩ series resistor to IN2 to limit bias current while maintaining valid voltage level - guidance explicitly stated in the Input Configuration section.
